RAIL-CLAMP.

Specification of Letters Patent.

' Patented May 21, 1912.

Application filed December 16,1911. Serial No. 666,119.

To allwhom it may concern;

Beit known that I, SAMUEL D. STEEL, a citizen of` the United States,residlng at IVoodla'wn, in the county of Beaver and' `State ofPennsylvania, have invented new and useful Improvements in Rail-Clamps,of which the following is a'specication.

The present invention -relates to clamps for rails.

Incarrying out my invention it is my purpose to provide a4 clampcomprisinga pair of elements arranged adjacent the opposite faces of therails and contacting with the head of theirail aswell as the baseflanges.

thereof, thesaid clamps being secured together in an effective and novelmanner which will prevent the displacement of the clamps even after thesecuring elements have been removed.

I also aim to provide a clamp of this char,

acter which may be secured towooden, plastic or metallicwrails, whichcomprises few parts and which will effectively sustain the rails againstlateral or downward movement.

With the above objectsand others of a similar nature in View, theinvention resides in the novel construction, combination and arrangementof 'parts hereinafter fully described and claimed. g

In the drawings, Figure 1 is an end elevation illustrating myimprovement applied to a rail. Fig. 2 is atop `plan View of the same.Fig. 3 is a sectional view upon the line 3-3 of Fig.- 2. Fig. 4 is a.perspective view `of one of the clamps. Fig. 5 is a top plan view of theplate. Fig. 6 is an elevation of the bolt. Fig. 7 is a top plan view ofone of the locking blocks. Fig. 8 is an elevation of one of theretaining rings. Fig.`

9 is a view of one of the pins. Fig. 10 is a transverse sectional viewillustrating the application of my improvement upon the ordinary angularfish plates.

Referring now to the drawings i ndetail, the numeral 1 designates atiefor railway rails. -This tie may he constructed of plastic materiah orwood or of iron, and the numeral 2desiguates what I term a tie plate,whichA may be formed with o1' which may be secured to the upper face ofthe tie 1 in any desired manner. rlhe plate is centrally formed adjacentits oppositeedges with spacedl elongated vslots 3 and the plate isfurther provided adjacent the walls formed by the said slots 3,withdepressions or open- The numeral 5 designatesa bolt. This boltcomprises a horizontal body-portion (i,r

and annular arms 7. The body 6 is arranged below the plate 2, and thearms .7 project through the elongated openings 3 thereof.

The numeral 8 designates the clamps. One of these clamps is arranged.upon each of the opposite faces of each of the rails, 'but as all of theclamps are of'siinilar conundercut to provide the angular wall' 10,

the same being of a shape conforming to 4the cross sectional contour ofthe base iange of the rail 11. The upper face of the base 9 isycentrallyprovided with a rib 12, the inner face of which-being verticallystraight, this rib e'xtends entirely across the plate 8,

and is centrally formed with an up-l .standing lug 13.

The lug 13, has` its inner face `vertically straight and is adapted toengage with the web upon one of the faces of the rail 11 while the topof the said lug is slightly inclined or beveled as at 14 so that thesame will engage beneath the ball of the rail 11. The body 9 of theclamp 8 is'centrally formed with an angular slot 15, the said slot isadapted toy receive the angular extending portions 7 of thel bolt 5. Thebody portion 9 of the member 8 is also formed with openings 16, whichyare adapted toregister with the vopenings .4 of the tie platevQ, andcommunicating with these openings and arranged at the upper face of thebody 9 are the enlarged recessed portions 17. The openings 16 and 3areadapted to receive a shank 18 and a headed pin 19, and

the head thcreof is adapted to bc'received within the recess 17 so thatthe pin will remain iush with the top of the body portion 9 wheninserted within the openings.

The numeral 20 designates lthe angular locking block. This block isprovided 'with a central opening 21, which is adapted to .permit of theblock beingpassed overthe extending arms y7 of the bolt 5. The blockwhen properly positioned tightly engages with the vertical faccofthe-rib l2, and

j permits of the inscrtionof a nut 22 upon one sure between the blockand the nut toprevent accidental removal of the nut from the .bolt dueto the vibration incident to the rolling stock passing over the track11.

It is here to be stated that the bolt 5 is constructed ot' some bendablematerial and from the above description taken in connection with' theaccompanying drawings it will be readily noted that even should the nuts22 be removed from the bolt the angular locking blocks, being retainedupon the angular arms of the bolt 5, will prevent the displacement ofthe parts and effectively sustain the rail upon the tie 1.

It will be furthernoted by reference to figures of the drawings that thespring. member 23 which I have termed a washer, is in reality more of akeeper when a pair of bolts 5 are employed as might be deemed necessary.when the clamps are employed upon T ties.

In Fig. 10 I have illustrated the device in connection with ordinaryangular fish plates. These fish plates 26, are connected through themedium of the usual bolt 27 and the nut 28. The clampin elements areprovided with longitudinal y extending upturned portions or beads 25,and the tie 29, in this instanceis illustrated as hollow. The sustainingelements are substantially similar to the device previously described.

ing with the ball 'and' we of the rail, a olt Y carried by the tie, saidbolt havingo positely disposed angular arms exten 'g *i through the bodyof the clamp,' wedge shaped locking blocks engagingthe pro- ;jectingportions of the bolt and adapted to contact with the ribs of the clamp,and nuts for the bolts. l

2. In combination with a tie, of a rail upon the tie, a bolt membercomprising a body and an ular threaded ends,a clamp having angu aropenings ,and adapted to engage the angular vportions of the bolt, saidclamp havi transversely arranged ribs, V-shaped loc 'ngblocks-contacting the upper 4face of the tie, and the ribs, and a nut engagingthe angular extensions of the bolt to compress the locking blocksagainst the ribs and against the clamp.'

In testimony whereof I afiix my signature" in presence of two witnesses.
